Am I wrong for being angry at my partner?

So my partner lives abroad and is currently awaiting his application to emigrate to my country to be accepted. My grandparents have kindly written a letter to say he can stay in their home with me when he arrives and borrowed us some of the money to support his application. My parents have found him a job when he arrives.
now my grandparents and my parents are going to my partners country for a holiday, and I asked him if he could stay with them and ensure they have a good experience and are ok. He has said no.
I’m not angry at him I’m absolutely disgusted! 1. It’s ungrateful 2. It’s selfish and horrible and 3. That’s my family he is not willing to help!
